The majority of cars use gas-burning engines, but concerns about air pollutions have rapidly brought electric motors into the market which rely on energy stored in batteries, and are pollution-free. In school, students should study the characteristics of electromagnetism : a magnetic field generated by an electric current. However, most of motor learning has not been in the education field and students do not recognize the importance of the motor. Therefore study of the electromagnet is greatly enhanced by actually building an electric motor and learning the interaction between electricity and magnetism. In the study, students make the magnets by themself, complete the PET bottle motor with the magnets, and run the car with the PET bottle motor engine by the clean energy. Students will understand the importance of eco-friendly energy through this learning.
